DAVID BRIAN, OF LOS ANGELES,

CALIFORNIA.

STEAM-GENERATOR FOR LIQUID-FUEL BURNERS.

To all whom it may concern:

Be it known that I, DAVID BRIAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Steam-Generators for Liquid-Fuel Burners, of which the following is a specification.

This invention relates to an improved form of steam generator for a liquid fuel burner, such as those burners which use crude oil or the heavier distillations thereof and use steam or other iiuid under pressure for at-omizing the liquid. And the prime object of the present invention is the provision of a generator which may be combined with any steam oil burner or the like and which, though simple and inexpensive in construct-ion, will act eiliciently to generate sufficient steam under pressure for operating the oil burner.

Broadly considered, my invention consists in a body of inverted U-section and larger at one end than at the other; this body having a passage therethrough in which water is heated and vaporized. The body is placed so that it will be over and around the fuel and flame discharge from the burner, the burner being placed at the smaller end of the body and the llame being discharged in fan shape through and beneath the body.

The above described combination is the main feature of my invention; there have been steam generators devised for oil burners but they have been arranged in entirely different manners from mine.

Another feature of my invention is the provision, in combination with the above explained feature, of a drip or generating pan located at the lower portion of the smaller end of the generator and immediately beneath the burner, so that, when the oil is first turned through the burner, it will drip down on to this pan and may there be ignited to initially heat the generator. Once the generator is heated and steam is generated, the operation of the burner proceeds in the normal manner.

There are other features of my invention which will be explained in the following specification and which are shown in the preferred form illustrated in the accompanying drawings, in which:

Fig. 2 is a horizontal section taken on line 2-2 of Fig. 3. Fig. 3 is a vertical longitudinal section taken on line 3 3 of Fig. 2. Fig. 4 is an end View of the generator.

In the drawings 5 designates a body preferably formed of cast iron or some similar material, being U-shaped in vertical cross section, as is best seen from Figs. 1 and 4. The body has a top portion 6 and side portions 7 and is wider horizontally at one end than at the other; so that, in its preferred form, the plan of the body is somewhat wedge shaped. The portions 6 and 7 of the body are sufficiently thick to inclose a circuitous passage 10 which enters the body at the lower portion of one of side portions 7 at the smaller end of the body, runs back and forth and upwardly along this portion 7 and then back and forth horizontally across top portion 6 and then back and forth downwardly along the other side portion 7 and emerges from the body at a point opposite where it entered. This passageway is continuous from end to end; but certain side passages 10a are provided which lead to the ends of the body portion and which are normally closed by plugs 11. These plugged openings provide at once means for cleaning the core sand out of the casting when it is made, and means for cleaning out the generator whenever that should become necessary.

At the lower portion of the smaller end of the generator body there is located a drip pan 2() which extends approximately half out beyond the end of the body and half beneath and within the body. This is best shown in Fig. 1. The passage way 10 passes out at each end through the bottom of this drip pan 20 as is indicated at 101 in Figs. 2 and 3. At the terminals of these portions l0b pipes 21 and 22 are connected to the passage way. Pipe 21. is the inlet pipe and leads from any source of water pressure, a chuck valve 23 being interposed to prevent any pressure passing back from the generator into the water system. The pipe 22 leads from the discharge end of the passage 10 in the generator and leads up to the liquid fuel burner 30. This liquid fuel burner may be of any desired design and character. Most liquid fuel burners of the character using steam or other fluid pressure have a fan shaped discharge. This is somewhat illustrated at 30a in Fig. 1. It will be seen that the discharge from the burner the heat of this combustion will generate sufficient steam in the generator to start the normal operation of the burner. Should the burner be shut down for a short time, there will be sufficient heat held in the generator to keep up a steam pressure therein, ready for use when the burner is turned on again. And to aid in holding the heat for the generator, as well as to partially divert the flame from all passing out of the generator, I have shown a baffle wall consist-ing of bricks 40 placed across the larger end of the generator near its bottom. These bricks, when heated, will hold av large amount of heat.

As a means of protection I have shown my generator equipped with a pressure gage 4l and a pressure release valve 42. Both the pressure gage and release valve are connected to a pipe 43 which connects they may be observed.

Having described my invention, I claim: l. In combination with a liquid fuel burner, a steam generator comprising a body of inverted U-section wider horizontally at one end than at the other, the smaller end being adjacent the burner so that the fuel discharge therefrom shall be through and beneath the body, there being a circuitous fluid passage through the body with terminals at the smaller end thereof, means to feed water to one end of the passage, and connecting means between the other end of the passage and the liquid fuel burner.

2. In combination with a liquid fuel burner, a steam generator comprising a body of inverted U-section wider horizontally at one end than at the other, the smaller end being adjacent the burner so that the .fuel discharge therefrom shall be through and beneath the body, there being a circuitous fluid passage through the body with terminals at the smaller end thereof, means to feed water to one end of the passage, connecting means between the other end of the passage and the liquid fuel burner, a drip pan attached to the lower portion of the smaller end of the body and beneath the burner, and a baflie wall across the lower portion of the larger open end of the body.

In witness that I claim the foregoing I have hereunto subscribed my name this 10th day of November 1911.
